This is to ensure that comment syntax in XML - which is a considerable
simplification - remains consistent with SGML syntax. See, e.g. [91] and
[92] here (by default, MDO is '<!', MDC is '>' and COM is '--'):

SGML allows *multiple* comments within a single comment declaration, each
comment delimited by a pair of double-hyphens. For the full syntax in
plain English, see e.g., Section 3.2.5 in RFC 1866:
